So, e.g. in the gcc.target/i386/sse4_1-pr88547-1.c testcase, we have before
veclower21:
v2di f13 (v2di x, v2di y)
{
vector(2) _1;
v2di _4;
[local count: 1073741824]:
_1 = x_2(D) <= y_3(D);
_4

Unfortunately the patch breaks quite a lot of tests on x86_64:
+FAIL: c-c++-common/goacc/firstprivate-mappings-1.c (internal compiler error:
in gimple_expand_vec_cond_expr, at gimple-isel.cc:249)
+FAIL:

For the testcase, having it in gcc.target/aarch64/sve as
/* { dg-options "-O2" } */
#include
svbool_t
foo (svint8_t a, svint8_t b, svbool_t c)
{
svbool_t d = svcmplt_s8 (svptrue_pat_b8

Oh, and one more thing, why the second hunk isn't inside of the if (assign && )
body, but after it?
If we haven't updated code, then it will never succeed with code = SSA_NAME
unless the first hunk already

Reduced testcase:
#pragma GCC aarch64 "arm_sve.h"
svbool_t
foo (svint8_t a, svint8_t b, svbool_t c)
{
svbool_t d = svcmplt_s8 (svptrue_pat_b8 (SV_ALL), a, b);
return svsel_b (d, c, d);
}
